The thermal conductivity of aluminum oxide is 15.06 W/mK at 75 (167 F) [8.71 BTU/hr - ft F]. Aluminum oxide has unique thermal conductivity qualities and features low loss factors at high frequencies. It has high compressive strengths, high volume resistivity, low thermal expansion and it resists radiation. -Attachment Methods - Note: Hole diameters are +/ otherwise specified. - Interface Materials - For TO - 3 - Accessories - Part Number RoHS - .13mm (.500"), angularity is +/ PCN A B C D E 39.70 (1.563) 26.67 (1.050) 13.34 (.525) 4.75 (.187) 30.40 (1.197) 44.45 (1.750) 31.75 (1.250) 15.88 (0.625) 7.16 (0.282) 30.15 (1.187) A B C D E 4169G* 19.30 (0.760) 13.97 (0.550) 4.78 (0.188) 6.98 (0.275) 3.68 (0.145) 4170G** 19.30 (0.760) 13.97 (0.550) 4.78 (0.188) 6.98 (0.275) 3.68 (0.145) 4171G** 16.51 (0.650) 12.70 (0.500) 4.32 (0.170) 6.35 (0.250) 3.81 (0.150) 4177G** 17.45 (0.687) 14.27 (0.562) 5.54 (0.218) 7.14 (0.281) 3.18 (0.125) 4103G* Useful Links * Building a part # * Catalog Request * Directions * Find Distributor * Find Sales Rep * How to order? * MSDS Safety Sheets * Part # Cross Ref * Quote Request * RoHS Initiative * Sample Request - 1 and flatness is .05mm (.002") TIR unless 4104* N/A *Thickness: 4103: 1.78 (0.070) to 2.03 (.080) 4104: 1.52 (0.060) to 2.03 (0.080) For TO - 220 Part Number RoHS PCN *Thickness 1.57mm +/ (0.004") TIR **Thickness 1.78mm +/ - 0.08 (0.062" +/ - 0.003"); surface flatness is 0.10mm - 0.25 (0.070" +/ - 0.010") For TO - 218, TO - 247, and TO Part Number RoHS PCN 4180* *Thickness:2.03mm +/ - .25 (.080" +/ - 3P A B C D E 23.24 (0.915) 18.80 (0.740) 6.98 (0.275) 9.40 (0.370) 3.96 (0.156) - .010") Insulating Covers TO- 3 Insulating Covers are designed to provide protection from accidental shock during field service or repair. 8903 Screw Mounted Cover Pan head screws not provided - MS 51957 - 30 or equivalent recommended - secure the cover to the TO At the typical mounting screw torque of .68 - .90 Nm (6 - 8 inch pounds), the TO - 3 cover material cold flows around the screw head to securely fasten the cover. - 3. - Included are No.6 split washers as inserts to provide electrical connection of mounting screws to the TO collector and an insulating snap - in cover for the screw heads. A test probe hole is provided in the top of the cover. The 8903VB is made from thermoplastic polyester that meets the requirements of UL Bulletin 94 V addition to its excellent flammability rating, thermoplastic polyester offers resistance to most chemical environments, heat deflection temperature to 215.6C (420F) and UL continuous use temperature of 130 C (266 F).
